About 260,000 people got insurance by shopping in the federally run Obamacare website in November, according to government numbers released Wednesday.

That’s about four times as many people who signed up for Obamacare in October, a sign that the federally run website for people to buy insurance is working better.

But today’s figures are just a fraction of the the 800,000 enrollments the administration had hoped for at this time of the year, underscoring the continuing problems with the federal website, HealthCare.gov.

Health and Human Services Secretary Kathleen Sebelius has called for an internal investigation into HealthCare.gov’s management. She will speak to Congress about this investigation today.

Today’s official numbers bring the total people who have signed up for health insurance on the federal exchange and state-run exchanges to 365,000. A Bloomberg News report had originally projected November enrollment figures at 100,000.

The administration is still hoping more people will sign up for health insurance on the exchange by Dec. 23, the deadline for people to get insurance before Jan. 1. People can still sign up for insurance through March.
